Symbol is a blockchain platform launched in March of 2021. It's the spiritual successor to [NEM](https://coinmarketcap.com/currencies/nem/), featuring a new consensus algorithm called proof-of-stake-plus (PoS+), rule-based tokens (called mosaics), namespaces, multisignature accounts, and aggregate transactions. Its client, [Catapult](https://github.com/symbol/symbol/tree/dev/client), is written in C++. Symbol has a cult following in Japan and Korea. The community can be primarily found on Twitter, LINE, and KakaoTalk. Some of the most notable projects built on Symbol include: * [QUEST](https://quest-bc.com/) | a bounty and tipping platform for creators. Follow the official Twitter account [here]( https://twitter.com/QUESTofficial5). * [SYMBOARD](https://symboard.tokyo/login.html) | a loyalty and rewards card for businesses. Follow the official Twitter account [here](https://twitter.com/symboard_symbol). * [THE TOWER](https://symvolution.com/thetower/) | a endless dungeon crawler. * [NFT DRIVE](https://www.nft-drive.com/) | a on-chain media and content storage service. Follow the official Twitter account [here](https://twitter.com/nftdrive_jp). * [COMSA](https://comsa.io/en) | a novel NFT marketplace developed and designed for the Japanese cryptocurrency community. In November 2021, Symbol was forked by a pseudonymous team of cryptocurrency experts and enthusiasts alike. Titled **Cyprus**, this hard fork signaled the community’s intent to turn Symbol into the world’s leading omnichain platform with content-specific, scalable shards - powered by [zk-STARKs](https://starkware.co/stark/). Symbol aims to solve for problems inherent in EVM-based platforms and omnichain solutions, where security is often defined at a smart-contract level (versus a network-wide level); where L2 validators are centralized and not incentivized; and where new features and functionality are decided by central client teams versus a fair and free market.
